Electrical air blower

ABSTRACT

An electric air blower includes a housing being composed of two symmetrical semi-housings. Each semi-housing has multiple feet formed at a lower side thereof, multiple notches respectively defined between the feet, multiple air inlets defined at a bottom plate thereof, a middle plate formed at a middle portion thereof, an upper plate formed at an upper portion thereof, and multiple air outlets defined through a top surface thereof. An air impeller is mounted between the bottom plates and the middle plates of the semi-housings. A motor is mounted between the middle plates and the upper plates of the semi-housings. An output axle of the motor extends downwards for driving the air impeller. A circuit board is installed in the housing and electrically connected with the motor. Thus, an inflatable toy fastened on the air blower can be continuously inflated by the electric air blower to attract passers-by.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an electrical air blower, and moreparticularly to an electrical air blower for pumping up an inflatabletoy or doll.

2. Description of Related Art

Inflatable toys or dolls are generally pumped up by an inflator or apump. The inflated toys should be detached from the inflator or pump andare used individually. However, air will gradually leak out from theinflated toys and thus they shrink, thereby needing to be pumped upagain. Thus, the prior art inflators are very inconvenient for a user.

Therefore, the invention provides an electric air blower to mitigate orobviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide an electricalair blower which can continuously blow air into an inflatable toy.

Other objectives, advantages and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1-2, an electric air blower (10) in accordancewith the present invention has a cylindrical housing being composed of afirst semi-housing (20) and a second semi-housing (30) attached to thefirst semi-housing (20) by fasteners (not numbered). The firstsemi-housing (20) and the second semi-housing (30) are symmetrical toeach other.

The first semi-housing (20) has multiple first feet (21) formed at alower side thereof and multiple first notches (22) respectively definedbetween the first feet (21). The second semi-housing (30) has multiplesecond feet (31) formed at a lower side thereof and multiple secondnotches (32).

With reference to FIGS. 1-3, the first semi-housing (20) has multiplefirst air inlets (23) defined at a bottom plate (not numbered) thereof,and the second semi-housing (30) has multiple second air inlets (33)defined at a bottom plate (not numbered) thereof.

A first middle plate (24) is formed at a middle portion of the firstsemi-housing (20), and a first upper plate (25) is formed at an upperportion of the first semi-housing (20). A second middle plate (34) isformed at a middle portion of the second semi-housing (30), and a secondupper plate (35) is formed at an upper portion of the secondsemi-housing (30).

A first bulb cap (26) is formed at a top surface of the firstsemi-housing (20), and a second bulb cap (36) is defined at a topsurface of the second semi-housing (30) and matches the first bulb cap(26) to form a bulb chamber (not numbered) for installing a bulb (70)therein. The first bulb cap (26) has multiple first elongated slots (27)defined therethrough, and the second bulb cap (36) has multiple secondelongated slots (37) defined therethrough.

A first semi-groove (28) is transversally defined at an outer peripheryof the first semi-housing (20), and a second semi-groove (38) is definedat an outer periphery of the second semi-housing (30) and matches thefirst semi-groove (28). Multiple first air outlets (29) are definedthrough the top surface of the first semi-housing (20), and multiplesecond air outlets (39) are defined through the top surface of thesecond semi-housing (30).

An air impeller (40) is mounted between the bottom plates of thesemi-housings (20, 30) and the middle plates (24, 34). A motor (50) ismounted between the upper plates (25, 35) and the middle plates (24,34), and has an output axle (51) extending downwards to drive the airimpeller (40).

A circuit board (60) is installed in the first semi-housing (20) andelectrically connected with the motor (50). The bulb (70) is installedin the bulb chambers being composed of the first bulb cap (26) and thesecond bulb cap (36). When the bulb (70) is turned on, light can passthrough the elongated slots (29, 39).

In use, an inflatable toy (80) with an opening (81) at a bottom thereofis provided outside the air blower (10). The bottom of the inflatabletoy (80) is fastened by a cord (not shown) in the grooves (28, 38).Then, when the air blower (10) is actuated, the air impeller (40) isdriven by the motor (50) to rotate, and air flows through the air inlets(23, 33) into the air blower (10) and is blown out through the airoutlets (29, 39) to inflate the inflatable toy (80). Thus, theinflatable toy (80) can be continuously inflated to float in air as longas the electric air blower (10) is actuated, and can be used as anadvertising mark to attract passers-by.

Moreover, the bulb (70) can be turned on to use the inflatable toy (80)at night.

It is to be understood, however, that even though numerouscharacteristics and advantages of the present invention have been setforth in the foregoing description, together with details of thestructure and function of the invention, the disclosure is illustrativeonly, and changes may be made in detail, especially in matters of shape,size, and arrangement of parts within the principles of the invention tothe full extent indicated by the broad general meaning of the terms inwhich the appended claims are expressed.
